RADIATOB FOR INTERNAL-COMBUSTION ENGINES.

Application filed August 25, 1919. Serial No. 319,797.

To alt 'zchom it may concern:

lie it known that l, CLEMENT G. BRAN- s'rnuron, a citizen of the UnitedStates, residing at Bushnell, in the county of Mcllonough and State oi?lllinois, have invented certain new and useful improvements in Radiatorsfor Internal- Combustion Enines; and it do hereby declare that thefollowing is a full, clear, and exact description oi? the invention,which will enable others skilled in the art to which it appertains tomake and use the same.

his invention relates to radiators for intei. a1 combustion engines. Itrelates more particularly to a radiator for an engine of the tractortype or "for other heavy duty.

in object oi my -vention is the provision of a new type of radiator forinternal coinbustion engines having a novel arrangement for cooling.

Another object of the invention is to pro- "ide a radiator of a form inwhich the cylinders of the on e can lie. immersed in water, suchradiator being supplied with a much larger bulk of 'atcr thancustomarily used, air-conducting tubes or pipes extending through thewater for cooling purposes.

In addition to the above objects the invention relates to certa ndetails of construetion that will be pointed out herein, it beingunderstood that what is shown is only one embodiment of the invention,sl it changes being possible without departing irom the spirit andintent ot the in vention.

To the end that the device may be understood in its entirety, l havefurnished the acco panying drai 'ing wherein- Figure l is the frontelevation of my radiator, showing two engine cylinders projecting fron'iits front face.

Figure 2 is a longitudinal sectional elevat on of the radiator showingone of the cylin ders.

Figure 3 is an enlarged detail, in longitudinal section, of parts shownin Figure 2.

Figure lshows in perspective certain details of construction of theradiator, and

Figure 5 is enlarged. detail of one end of a cylinder and the means formounting it water-tight in a wall of the radiator.

iii represents two frame portions of the tractor or other type ofvehicle (not shown) between which is mounted a receptacle or pan B forwater, .the same being provided with longitudinal flanges C to rest uponsaid frame portions and bolted thereto in any suitable manner. DDrepresents two cylinders as a part of an engine, whose ends ex tendthrough the front and rear walls of the said receptacle Band securedtherein in some such manner as is now to be described. TY

ihe front end or the cylinder ES provided with a flange abutting againstthe "front all oil? the receptacle, adjacent surfaces or" the flange andwall having annular grooves to receive a packing ring F to provide awater-tight joint. (51G are the heads of the cylinders, from each ofwhich may extend the exhaust and intake manifolds H and J respectively.K represents a series of bolts passing through the flange of the head,the flange E and the wall of the receptacle se curing the whole firmlytogether, wiile L represents a packing ring let into grooves in theadjacent surfaces of the head G and flange E in order to provide agas-tight oint. l

The rear ends of the cylinders are preier- :rbly reduced in diameter asin Figure 5 where they pass through the radiator wall B and the outersurface of said wall is provided with a recess M to receive a packingring N, as clearly shown in this figure, there being aplate or ring 0bolted to the wall and adapted to compress the packng ring N and forceit against the cylinder wall whereby to make an entirely watertightjoint. 7

PP represents two flanges extending from the under side of thereceptacle B adapted to receive between them a saddle-block Q, clearlyshown in Figure i, said block being secured in any usual manner to thespring indicated at R, a pin S serving to secure the flanges P and theblock Q in pivotal manner. As clearly shown in Figures 2, 3 and 4;, thereceptacle B of the radiatoris provided with an inwardly projectingflange at its top edge denoted at T. U is a box preferably of sheet ironhaving an inwardly directed flange V extending around its lower edge,which rests upon and is secured to the flange T, there being interposedbetween the two flanges a gasket W in order to form a tight joint. Thesaid box is constructed so as to be entirely eater-tight and is providedat its top with a wall 3. a indicates a series of vertical tubes orpipes opening through this said wall and through the bottom of thereceptacle B, the ends of the pipes or tubes beingsuitably turned overor swedged at their ends to make a water-tight oh. 5 indicates an anglebar at each corner of the box to properly brace it, their lower endsbeing firmly bolted to the receptacle B, as indicated in Figures 1 and2. 6 is a hood covering the top of the re diator for carrying awayexhaust gases and steam, the described exhaust manifold H being extendedinto said hood in the usual manner and perforated at 7, Figure 2.

S is a drain cock let into the bottom of the receptacle B by which watermay be drained from the latter if desired. The receptacle B and thedescribed. box is filled with water to a considerable height, it beingnoted that the cylinders D are immersed in the water. It is furtherobserved that some of the pipes or tubes are disposed each side of thecylinders and between them and provide air passages from beneath theradiator up through the water and out of the hood 6 for coolingpurposes, strong draft being induced through the pipe due to the exhaustpipe H. The number of tubes or pipes may be as great as desired, thisbeing possible by increasing the size of the radiator receptacle andbox, or other arrangements of the pipes may be made for the purpose.

The top wall 3 of the radiator box is perforated at c for permittingsteam to escape into the hood, loss of water by evaporation or steamingbeing made up by the use of a filler cap 9, through which water may beintroduced into the radiator.

The very large surface of the box exposed to the air, together with thesurfaces exposed by the flues, act to keep the water properly cooled,even though the cylinders are emersed in the water. As constructed,

my radiator is thoroughly strong and rigid and therefore cannot easilybe damaged even under the most severe usage in the field. I have neithershown nor described the igni tion system or any of the other parts ofthe engine, since these do not enter into the present invention, whichrelates wholly to a radiator and to a radiator having engine cylinderstherein.

The sheet iron box is preferably employed because it provides thin.walls for quicker radiation, in addition to the fact that it is muchlighter than those of heavy cast or wrought metal.

I claim:

1. In a motor vehicle, the combination with theengine cylinders thereof,of cooling means therefor comprising a vessel having end walls in whichthe respective heads of said cylinders are sealed, a cooling fluid insaid vessel, vertical cooling pipes extending from the top to the bottomof said vessel on each side of each cylinder, an exhaust hood secured tothe top of said. vessel, and an exhaust pipe extending into said hoodfor causing a circulation of air through said pipes.

2. In a motor vehicle, the combination with the engine cylindersthereof, of a cooling radiator therefor comprising closed vessel forsupporting said cylinders with the ends of said cylinders sealed in theend walls thereof, a plurality of vertical cooling pipes on each side ofeach cylinder, said pipes extending through the top and bottom walls ofsaid vessel, a cooling fluid in said vessel, and means for inducing anair draft through said pipes for cooling said fluid.

In testimony whereof I affix my signature in presence of two witnesses.

CLEMENT G. BRANSTRATOR.
